If the encircling scleral buckling is necessary?——a discussion of operation in rhegmatogenous retinal detachment with vitrectomy

Objective To evaluate the effect of encircling scleral buckling operation in rhegmatogenous retinal detachment(RRD) with vitrectomy. Methods A total 140 eyes suffering RRD(without macular hole) which experienced once vitrectomy were studied,including 79 eyes with scleral buckling and 61 eyes without scleral buckling.The differences of the reattachment rate and the improvement of visual acuity between the two groups were compared. Results The retina reattched in 67 eyes(84.81%) of buckling group and 52 eye(85.25%) of nonbuckling group.There was no statistical significant differences in the rate of retinal reattachment between the two groups.Differences in PVR grade and positions of the retinal tears can lead to an identical outcome.Rate of improvement of visual acuity in buckling group is 79.75%(63 eyes),while which in nonbuckling group is 80.33%(49 eyes).Significant difference can not be found. Conclusion The scleral buckling operation is not a necessary procedure to improve the rate of retinal reattachment in RRD with vitrectomy,while perfect vitrectomy and effective intraocular tamponade are the key factors.
